<p>我在我的数据中有一列变量的顺序不正确，我需要改变它们的顺序以正确地可视化渲染。</p> <p>我提供了一个可重现的示例，以便更容易理解：</p> <pre class="brush:php;toolbar:false;">library(reactable) library(dplyr) species <- c("setosa", "versicolor") df <- iris %>% filter(Species %in% species) numbers <- c( 100, 300,400, 50) type <- rep(numbers, times=25) df1 <- df %>% mutate(type = type) df2 <- df1 %>% mutate(species_type= case_when(Species == "setosa" ~ paste0(Species,": ", type), Species == "versicolor" ~ paste0(type,": ", Species), TRUE ~ Species )) columns <- list(colDef(minWidth = 140), colDef(align = "center")) columns <- setNames(columns, names(df2)[2:3]) reactable(df2, columns = columns)</pre> <p>我需要在渲染的表格中对species_type进行排序，使得带有50的species_type首先出现，我有一个预先计算好的数据框，其顺序与上面的示例相似。然而，我尝试在渲染之前进行排序，但是在表格中仍然得不到正确的顺序。 我应该如何做？我尝试了排序，非常感谢！</p>

library(reactable)
library(dplyr)

species <- c("setosa", "versicolor")
df <- iris[c(1:4, 51:54), ] %>
  select(Species) %>
  filter(Species %in% species)
numbers <- c(100, 300, 400, 50)
type <- rep(numbers, times = 2)
df1 <- df %>% mutate(type = type)
df2 <- df1 %>
  mutate(species_type = case_when(
    Species == "setosa" ~ paste0(Species, ": ", type),
    Species == "versicolor" ~ paste0(type, ": ", Species),
    TRUE ~ Species
  ))

columns <- list(colDef(minWidth = 140), colDef(align = "center"))
columns <- setNames(columns, names(df2)[2:3])

df2 %>
  arrange(type) %>
  reactable(, columns = columns)

reactable(df2, columns = columns, defaultSorted = "type")
